Not sure this is what your looking for:
The windows events are mapped back to signature for example. If you take a look at the sig you will notice the last 3-5 numbers correspond to the windows event ID.

The other suggestion would be to modify the Windows Parsers to capture the windows event ID into a searchable field and then you would be able to search the field for the event id.
You're able to search for Windows Events directly from the Global Filter. As mentioned, you can decode and guess the Sig-ID for the Windows event, or you can click the Windows tab and enter the Event ID there. The challenge is that some Windows Event IDs aren't necessarily unique so this less than obvious method allows you to select the correct application that the ID is referring to.
